UNITED STATES PATENT OFFICE.

JOHN MECAY, OF MILLSBOROUGH, PENNSYLVANIA.

IMPROVEMENT IN WATER-WH EELS.

Specification forming part of Letters Patent No. 4,332, dated December 26, 1845.

To aZZ whom it 'may concern.-

Be it known that I, JOHN MECAY, of Millsborough, in the county of Washington and State of Pennsylvania, have invented a new and useful Improvement in Water-VVheels, which is described as follows, reference being had to the annexed drawings of the same, making part'of this specification.

Figure l is a perspective View of the wheel as arranged inthe scroll-case, the upper section of the case being removed. in order to show the wheel. tudinal section through one of the wheels and case. Fig. 3 is a vertical transverse section through both wheels and part of case.

This invention and improvement consists in combining and arranging upon a horizontal or vertical shaft A two percussion and centripetal reaction water wheels B, surrounded by a scroll-case C of the ordinary description, so as to conne the water around the peripheries of said wheels. The wheels are made of cast iron, and consist ot two metallic bulk-heads or rings E, having four or more curved buckets D placed between them on a line tangential to the inner peripheries of the rings or bulk-heads E, slightly curving inward until they reach theouter peripheries of the rings, where they slightly curve in-a reverse direction, as represented at fr, Fig. 2, and firmly secured in their positions by bolts passing through the rings by which they are Fig. 2 is a vertical longidrawn toward each other and caused to clasp the buckets D. A metallic bulk-head or plate F, Fig. 3, is placed midwaybetween the rings E for dividing the buckets into two apartments, thus forming two wheels on the same shaft.

The Water in passing around the scroll-case @surrounding the wheels, strikes the curved part or verge fr of the buckets and forces the wheel in the direction that it enters, and having passed into the scroll-case fills the space between the Wheel and the case, and then acts against the convex surfaces ot the buckets D and escapes or issues from the wheel to the center centripetally, causing the wheel t-o turn in a direction contrary to the escape of the Water from the buckets.

The wheel may be made of wood or metal, or any part thereof, and placed in a horizontal, Vertical, or inclined position.

What I claim as my invention, and desire to secure by Letters Patent, is-

' The combining with the spiral scroll the projecting portion of the buckets, (marked in the drawings,) and in combination with the foregoing the arrangement of the buckets,

,substantially as herein described and set forth.
